Oh.. wait, what?
The Pirate films are action/adventure with some comedic elements, not comedies.
Orlando Bloom and Kiera Knightly weren't exactly wise cracking it through those films.
As For Rebel Wilson, I totally could see them putting her in the film. In scenes where it seems they didn't have a script and just told her to ad lib lines on a set before the scene just kind of ends. The last film was filmed in Australia, their COVID response has been good, so it'd be much easier to get a film intro production there sooner than most other parts of the world. Which would then mean lots of Australian actors.
